One way of creating such text without a plug-in would be using a 3D Grahic/animation program such as Cinema4D.
Create your text and animate it to go across the screen, but leave the text at 255 Green. Render it and put it into Vegas. Put another layer with your video below the text. Apply the Chroma Keyer plug-in to the text, add some techy music, and you have something somewhat similar. Once you get the basic of it down you can start playing with it and experimenting with different ideas that may also be based on this idea.
Cinema4D is rather pricey if your only going to use it for a small graphic here and there, but I didn't say anything about file-sharing.
